Summer exploration activities and environmental studies are in full swing for 2010 at the Pebble deposit.

Currently, two drill rigs are in 24/7 operation that include local participants from the Pebble Partnership’s Driller’s Apprentice Program. A wide variety of research and survey crews are on site totaling more than 120 workers, which is welcome news for people in the region ready to go to work.

Several geological studies are currently inprogress,includinganiPsurvey,

There is also no basis for this speculative claim.infact,thetrackrecord for Alaska’s existing hard rock mines tells a completely different story.
